PEX-AL-PEX Over-lap Welding Pipe Production Line

This plastic pipe extrusion line is used to manufacture PEX-AL-PEX, PERT-AL-PERT, PPR-AL-PPR pipes. 
This kind of composite pipes have some good characteristics, such as no deformation under high temperature and pressure in long time; excellent oxygen resistance, high mechanical properties, sanitary, corrosion resistance, long termal conductivity, long life span etc. It's suitable for building systems in hot and cold water, floor heating ystem and air conditioning system.

Process Flow of PEX-AL-PEX Over-lap Welding Pipe Production Line:
Al plate unlocking → Al plate forming machine → Pex material→Vacuum Feeding → Single screw extruder → Single screw extruder → Co-extrusion mould → Al plate ultrasonic roll welding machine → Single screw extruder → Single screw extruder → Co-extrusion mould → Dip-in cooling tank → Dip in cooling tank → Spray code printer → Belt haul off → Double winder → Steaming for 24 hours → Finished product inspecting& packing

Feature of PEX-AL-PEX Over-lap Welding Pipe Production Line:
1. By adopting precision forming technique of aluminum tube, ultrasonic welded aluminum tube will have precise size and nice roundness.
2. By adopting the process of co-extrusion in steps for inner and external tubes, binding strength between tubes is increased, heat accumulation between tubes are avoided, hence, ensure a more smooth surface of both inner and external tubes.
3. PLC control system is adopted by this production line, it has friendly human-computer dialogue interface, easy to operate and with interlock function. 
This production line is used to manufacture aluminum plastic tubes and aluminum tubes. Laminated tubes will be formed in one step by ultrasonic welding and Co-extrusion process. Such aluminum and plastic laminated tubes are widely applied for cold and hot city water pipes and running pipes of acid, alkali, salt, other kinds of liquids, fuel gas, oxygen and compressed air etc.
